AN ACOUSTIC APPROACH TO EVALUATE PRESENCE AND ECOLOGICAL STATUS OF CETACEANS IN THE IONIAN SEA
Cetaceans are among the biggest top-predator species and their presence is therefore a useful indicator of the health status of marine environment. Variations in their presence and distribution in a given area, such as the Mediterranean Sea, potentially highlight environmental alterations driven by...

Cetaceans are among the biggest top-predator species and their presence is therefore a useful indicator of the health status of marine environment. Variations in their presence and distribution in a given area, such as the Mediterranean Sea, potentially highlight environmental alterations driven by either biological, chemical, physical or anthropogenic factors. Hence, the development of new cetaceans monitoring techniques actively contributes to promote good management practices of water resources. Since 2005, the INFN (Istituto Nazionale di Fisica Nucleare) has promoted, within the framework of the EMSO and KM3NeT projects, the installation and operation of two cabled deep-sea infrastructures offshore Eastern Sicily, Ionian Sea: the Catania node, at a depth of 2,100 m, 25 km offshore the harbour of Catania and the Capo Passero node, at a depth of 3500 m, 100 km offshore Portopalo di Capo Passero.
